SASL and PSYC

Should it make sense to use a SASL compliant procedure built into Spec:Linking? Probably. In fact it would be ideal if it were a generic authentication scheme to log into an identity (by using a context subscription protocol into an identity's channel of locations), but if in any way useful also allow a password-oriented approach to entering chatrooms or whatever context you can think of. Also logging in into multiple identities may be useful, and it may even want to happen at the same time over the same circuit. The circuit should thus remain a usage independent highway for packetrouting, even if there is an authentication exchange happening between two entities at the ends of this circuit. It may also happen at any point in time since the creation of the circuit.
